Aeration with sprinklers, the water jet comes out from the nozzle with high velocity and falls into the water in drops, thus contacting the air on a large surface and dissolving oxygen from it. When the water drops hit the water surface of the pond turbulence occurs increasing the diffusion of air into the water. The water jet nozzle is directed down into the water at 45 degrees helps to mix DO to the bottom of the pond and creating a regular flow of water. Water jet nozzle placed parallel will help to maintain a steady stream throughout the pond. Major benefits of sprinkler aerator is the low operational and maintenance cost which in turn reduce the production cost. Nil animal mortality, no oil leaks, runs 24x 7, water taken from bottom of the pond and circulated, equal distribution of DO. Sprinkler aerator can be used both in fish and prawn farms.
